To all wh om 'it may concern: V

Be it known that I, CHARLES S. Loonwoon, .a citizen .of the United States, resid ing at 289Marketstreet, Newark, county of.

Essex and State of New Jersey, have inments in'Combination Roller-Bearin s, fully described and representedin the fo ilowi ng specification and theaccompanying drawings, forming apart of the same.

' This invention relates to a self-contained roller-bearing in which two series oLeonical rolls are fitted to inclined conical seats upon opposite ends of the same hub, and embracedby' tapering seats within opposite ends of a casing. In such constructions, the end-thrust of the hub within the casing operates to contract the space between one-seat on the hub and the opposed tapering seat in. the casing, so that the rolls in their rotat-ion in such space tend to crowd toward thecenter part of the casing; and the object of the invention is toprovide a means of resisting such end movement'of the rolls with a minimum of friction, and of sustain-.

ing such thrust from either series of rolls independently of the opposite series. This is accomplished in the present construction by inserting a thrust-ring or rings to turn of such ring, and inserting one or more series of balls between such thrust-ring and a ball-race or races upon the hub to resist end movement of the ring. The hub is preferably formed with a channel between the bases .of the opposed conical seats with a ball-race in such channel contiguous to each slight variations of velocity 'initlie move-- ment of the -rolls, and the. separate rings which touch their bases. One of the conical seats upon the hub ispreferably made ad-* justable toward the other so as to adjust the ball-races in the channel toward .one an- I other to fit the rings snugly upon the inter- -mediate series of balls, and one of the tapering seats in the casing is preferably made adjustable toward the opposite taperin seat to fit such seat snugly to the outerjsi esof certain new and useful Improveball-races upon its opposite edges.

ing' the seats-upon the hub and in the casing when suitably the rolls upon their seats.

The annexed drawing shows an embodiment of the invention Figure longitudinal section :ot a bearing, where hatched Fig. 1f" is a cross section of two thrust-rings in contact;- and Fig. .1 is a cross section of a single thrust-'ringFwith is a section on line 22 vin Fig. 1; Fig. .3 shows the end of the collar which is adjustadjusted, .and for guiding" 1 being a v able with one of the conical seats upon the:

end of, the hub; Fig. 4' shows the end of the hub upon which such ring is fitted; Fig. 5 is an-elevation of the hub; Fig. 6 shows the inner side ofione of the thrust-rings which engages the contiguous 'endS of the rolls;'-

and Fig. 7 is a perspective view of the key collar upon'the hub.

The casing A is shown as a cylindrical shell with a shoulder 'B inside of one end to which a ring-section C is fitted, and pro vided'with a tapering seat Dto support the rolls a. The casing is threaded internally at the opposite end and provided with. .a threaded ring-section ()"having a tapering seat D to embrace the opposite series of rolls a. A notch F is shown at one end of the casing and'a screw G which is tapped into the periphery of the ring-section C and its head'fitted to such notch to hold the ring from turning when adjusted. The adjustment is permitted by a series of ta holes in the ring-section as shown'at H in .1

Fig. 2. This construct-ion secures the smalland the r1ngs.C and C of plain steehcollars- The hub shown in Fi s. 1 and 5 has an integral conical seat 12 tormedxthereon near one endwith a solid integral. collan at the outer or smaller end ofsuch seat, which forms an inner shoulder of next the smaller ends of the rolls and. an outer shoulder d wliilich'is employed to guide the cage for the ro s. posite the seat-b with afthreaded boss I, and a collar J screwed thereon'and formed with tapering conical seat I which has inner and outer shoulders c and cl near its outer end,

like the seats I).

The bases of the conical seats project above the central portion of the hub leav- The hub is formed near the. end opits ' ing a channel K, the opposite ends of which are, rounded to form. ball-seats e to which two'series of balls e are fitted."

Thrust-rings f are iormed each upon its inner side with a ball-race e shown in F ig.

6,-to fit the balls e, and the adjacent ends .of the rings are formedwith. opposed ballraces to fit an intermediate seriesof balls 9. The ends of-the rollsa, a, are beveled to fit the outer'ends of the thrust-rings f.

'The threaded connection of the seat I) with the hub permits the adjustment of the ball-races e toward one another, 'which,

cronds the rings 7 slightly together to snugly embrace the intermediate balls This holds the thrust-rings.to rotate in a fixed path, and enables the rolls a, a, to be perfectly supported by such 'thrustq'ings in opposition to any tendency to end ,movement.' 1

i To secure the seat b upon the hubgwhen adjusted, either the boss I or the ring I is provided with a series 'of keyw'ays h 'asshown in Fig. 4, and the connecting part with a single keyway 11, which permits a key j'to be inserted when the keyway z is in co-' incidence with either of the keyways h, thus -locking the seat 6 securely upon the hub.

The screw 9 serves in like manner to lock the adjustable seat in the casing to its working position,

"excepting that the two series of rolls are has an innercollar fittedto turn freely upon provided with independent cages andeach the outer side of one of the thrust-rings. Each cage is shown with an outer collar Z fitted to one of. the shoulders d or d upon the'hub an inner collar m of considerably larger diameter, and inclined bars k which connectthe two collars on a line with the axes of the rollsand thus-touch their opposite sides on the line of their centers.

To support the inner collar m, it is rovided with a supplemental collar m of smaller bore fitted-movably to the exterior of the adjacent thrust-ring f, the cage being thus supported at' both ends and held m a concentric path about the axis of the bearing. a

Fig. 1 shows a modification of the construction in which the thrust-rings f have their adjacent faces in contact with one another without any intermediate balls as 'in Fig. 1, but if the parts in one end of the bearing are constructed precisely like the parts in the opposite end, it is obviousthat the two thrust-rings would revolve at the same speed and would need no means (like balls); interposedbetween them to compen- .sate for variations of speed, and may, therefore, be united in a single ring f with ballraces e upon its opposite ends as shown in Fig. l. I have, therefore, claimed the thrust-ringfitted between the series of rolls andheld movably upon the hub by balls 4 fitted to a suitable race.

The adjustment of the collarJ upon the hub, with one of't'he conical seats 2).,- is for the obvious purpose of bringing the ballraces e into such a relation to the thrustrings asvto hold the thrust-rings from endplay, while such rings adequately support the thrust of the rolls a and a, and such an adjustment of the parts performs the same function as the thrust-rings f touching, as

in Fig. 1, or as the single piece 7 with gall-races upon its, opposite edges, as in i l a i Iaving thus set forth the nature of the invention what is claimed herein is:
